100% and I’m a software developer and have been for ~30 years. Good QA people know how to find regression and bugs _that you didn’t think about_ which is the whole reason why it shouldn’t be under “engineering” and that it should exist. One of the QA people I work with currently is one of my favorite people. They don’t always make me happy (in the moment) with their bugs or with how they decide to break the software, but in the end it makes a better, more resilient product.
